Safety Precautions Read entire section before starting installation WARNING! Electric Shock can kill – Only qualified personnel should perform this installation. Turn off input power at the fuse box before working on this equipment. Do not touch electrically live parts. Always connect the machine to an earthed mains supply as per national recommended standards. -
Page 6: Electrical Installation
Read and follow the ‘Electric Shock Warnings’ in the safety section if welding must be performed under electrically hazardous conditions such as welding in wet areas or water on the work piece. Electrical Installation WARNING! ELECTRIC SHOCK CAN KILL Machine grounding and High Frequency Interference Protection This welder must be grounded to earth. - Page 7 Allow machine to sit for 5 minutes minimum to allow the power capacitors to discharge before working inside this equipment. Do not touch electrically live parts The TIG160PDC Inverter Tig Welder requires a 240V 50/60Hz 13amp fused supply. It comes with a 3 metre mains cable attached.

Page 11: Controls And Settings
Controls and Settings Fig 4 1. Up slope Adjustment 0-5 seconds. The main welding current raises from minimum amperage to main current selected in time selected when weld started 2. Down slope Down-Slope adjustment 0-5 seconds. The main welding current decreases from main amperage to minimum amperage in time selected when weld finished 3. - Page 12 4. Pulse frequency adjustment This sets how often pulse will occur and is adjustable from 0.5Hz to 25Hz. 5. Gas post flow adjustment Adjustable from 1 – 10 seconds. The gas keeps flowing after weld has finished, this cools & stops tungsten from getting contaminated.
- Page 13 When the trigger mode is in the 4 step position the following sequence will occur Press and hold the tig torch switch to start sequence. The machine will open gas valve to start flow of shield gas, after a 0.5 seconds pre-flow time to purge air from torch hose the welding output of machine will be turned on and the arc will be started.
